When you see "... the following ...", that means there's supposed to be a list of choices. I'll bet it was right there next to this question as you were copying, and you decided not to share it.
On paper or in the real world, 'x' must be 15 .
Mathematically, 'x' can also be -20 .
A) growth; B) decay; C) growth; D) decay
A is growth because the value of b raised to the exponent is larger than 1.
B is decay because the value of b raised to the exponent is smaller than 1.
C is growth because the value of b raised to the exponent is larger than 1.
D is decay because the value of b raised to the exponent is smaller than 1.
Answer:
All are correct
Step-by-step explanation:
If Friend A gives 145 and Friend C gives 245 they already have a total of $390 out of the $700. So the missing amount is 310, half that for both friends and get 155, so the last 2 could both pay 155. No matter which way you put the number you will get the same answer. And as the communitive property states "The numbers on which we operate can be moved or swapped from their position without making any difference to the answer." and all of the answer choices apply to that statment.
We would multiply $30 by 5% to first find 5%
5% = 0.05
$30 x 0.05 = $1.50
Now we add that to 30
$30 + $1.50 = $31.50
Your answer is $31.50
